Hi

Your current config is:
1 firewall: blocking communication between 172 & 10
2 routing: blocking routing between 172 & 10

But want them to be able to communicate, right ?

Start by removing all those listed rules: 2 firewall rules and 4 router rules.

"Default config" should be enough then. If not, please list your config:
/export hide-sensitive

I don't see anything out of ordinary:

No firewall rules (except nat masq) => all is ACCEPTed
routing table no non-default entries: so should include connected routes for each network + default gateway from dhcp-client
=> please verify that?

So, should be working as is.

Few other remarks to look into later, but non-blocking:
* there is no need for a bridge with only 1 device in it
* interface list isn't in sync with bridge config, but currently not used
* dhcp pool naming scheme <> dhcp-server naming scheme???

The inter-network (172 <-> 10) communication should be working as is. How did you verify that it isn't?

What have you tried? Could you explain how "it is not working"?

I'm asking as from pure router configuration, the network level communication is allowed.

Few things to check:
* can client & server connect to internet (=> this would indicate that they have proper network configuration)
* can you ping between 192 & 10, to any other system, if necessary disable temporary firewalls
* do you have some kind of filtering on server or client? (=> server-client works on 10 both, but not on 192)
